  • Page 11: Receiving Satellite Signals

    Receiving Satellite Signals For TracVision G8 to receive satellite TV signals, the antenna must have a clear line of sight to the satellite. If you only receive intermittent signals or the antenna cannot find the satellite, check around your vessel for any objects that could be blocking the signal, such as other vessels, trees, buildings, other onboard equipment, etc.

For example, since the data/power cable is 100 ft (30 m) long, the MCU must be located within 100 ft (30 m) of the antenna.

  • Page 26

    TracVision G8 Owner’s Manual - Guide to Technical Information • To minimize tracking errors, place the antenna unit as close as possible to the intersection of the vessel’s fore- and-aft centerline and midships. In addition, do not mount the antenna too high off the water (limit height above the waterline to less than half the vessel length).
